This device adds moisture to the indoor air, like a purifier there are two main types of humidifiers. A furnace humidifier attaches to the HVAC system, while a point-of-use humidifier is for one particular room. Low humidity occurs during the winter season in artificially heated spaces. Lack of humidity causes the mucous membranes within the lining of the nose and throat to dry out, which causes respiratory distress. The suggested relative humidity for most homes is 30% – 50%. If the relative humidity raises to excessive levels then your home becomes much like an incubator for the growth of dust mites, mold, and hypersensitivity pneumonitis. You should have a properly installed hygrostat to monitor and control humidity levels automatically. Our professionals at Delcor can assist you with a humidifier selection and installation process.
